Grapefruit corer



T. J; M KINNON GRAPEFRUIT CORER July 4, 1950 Filed March 26, 1947 INVENTOR ATTORNEYS Patented July 4, 1950 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to a device designed for coring grapefruit, the primary object of the in vention being to provide a device of this character which when positioned over the core of a grapefruit, and pressed downwardly, will actuate a pair of blades which move into cutting relation with each other, cutting the core from the grapefruit.

An important object of the invention is to provide a device of this character which will not only cut the grapefruit core from the grapefruit, but will retain the grapefruit core in the device between the blades, so that the core may be removed with the removal of the corer.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing,

Figure 1 is an elevational view of a grapefruit coring device constructed in accordance with the invention.

Figure 2 is a sectional view taken on line 2--2 of Figure 1.

Figure 3 is an elevational view partly in section, illustrating the position of the blades and handles, during the core-cutting operation.

Figure 4 is a sectional view taken on line 4-4 of Figure 1.

Figure 5 is a sectional view taken on line 5-5 of Figure 1.

Referring to the drawing in detail, the corer comprises a pair of pivotally connected cutting sections, each section embodying a pair of spaced arms 5 connected at their outer ends, by means of a curved cutting blade 6 which is disposed at right angles with respect to the arms 5, so that the blades will move towards and away from each other, by the movement of the arms.

As clearly shown by Figure 3 of the drawing the sections are so arranged that one section will operate within the other, the sections being connected by the pin 1 which provides the fulcrum for the arms.

The handle of the corer, comprises a pair of sections 8 which are identical in construction, the sections 8 being pivotally connected at their outer ends, by means of the pin 9. These sections 8 embody lengths of sheet metal material, curved longitudinally, to provide convenient grippng surfaces, the ends of the sections being cut away as at In providing ears H, which are formed with openings to receive the pivot pins between the handle section and arms of the blades.

Pins l2 extend through the ears I I at the inner ends of the handle sections, and connect the handle sections to the arms 5 of the blade sections.

A coiled spring indicated at I3 is coiled around the pin 9, the ends of the spring contacting with the inner surfaces of the handle sections, at the points spaced appreciable distances from the pin 9, as clearly shown by the drawing.

This spring acts to normally urge the sections of the handle to the position as shown by Figure 3 of the drawing. Shoulders [5, are formed adjacent to the blade ends of the arms 5 of one of the Blade sections, the shoulders adapted to engage the upper edge of the adjacent curved blade, to provide stops to restrict movement of the blade sections, in one direction.

From the foregoing, it will be seen that due to the construction shown and described, the corer when in the position as shown by Figure 1 of the drawing, may be forced over the core of a grapefruit, and the handle section forced downwardly, causing the arms of the blade sections to move in such a way that the blades will be moved into cutting relation with respect to each other, cutting the core from the grapefruit.

By elevating the grapefruit corer, the core may be removed, and the grapefruit further out for serving.

What is claimed is:

In a corer, blade sections, each blade section comprising a pair of curved spaced arms and a transversely curved blade member connecting each pair of arms, means for pivotally connecting the blade sections at points adjacent to the blades, shoulders formed on the curved arms of one blade section, said shoulders being engageable by the rear edge of the adjacent blade section restricting movement of the blade sections with respect to each other in one-direction, a pair of handle sections pivotally connected at their outer ends, means for pivotally connecting said handle sections to said blade sections where,

by pivotal movement of the handle sections in one direction moves the blades of the blade sections into cutting relation with respect to each other.
